The Blue Planet Aquarium of Cheshire Oaks, England, is proud to announce the successful breeding of the aquarium’s resident splash tetras, a small species of fish native to South America. The success is so unusual because this particular species of fish lays its eggs outside of water, typically on the underside of a low-hanging leaf above the water’s surface.
The male splash tetra surveys an area to be sure its suitable for the impending brood; once he finds it, he fans his colorful fins to attract the female. Together, they leap from the water and attach to the leaf through suction created by their fins, after which the female lays her eggs and the male fertilizes them. The process repeats until the female has laid all of her eggs, usually to the tune of hundreds.
